presents
the
brand
new
5
1/2
Digit
Dual
Measurement
Multimeter-GDM-8351
to
replace
GDM-8251A
ofthe
same
category.
GDM-8351
eatures
VFD
dual-display,
maximum
120,000
counts,
0.012%
basic
DC
voltage
accuracy
and
USB/RS232C
connectors
to
provide
users
with
measurement
precision,
lucid
data
observation,
and
the
convenient
connection
with
the
personal
computer.
In
addition
to
the
fundamental
measurement
items
such
as
AC/DC
voltage,
AC/DC
current,
AC+DC
voltage/
current,
2W/4W
resistance,
frequency,
temperature
measurement,
continuity
beeper
and
diode
test,
GDM-8351
also
equips
with
the
capacitance
measurement
function.
Furthermore,
the
GDM-8351
also
provides
many
auxiliary
functions,
including
maximum/
minimum
values,
dB,
dBm,
compare,
reading
hold,
algorithms
(MX+B,
1/X,
%)
etc.
to
meet
the
measurement
requirements
for
manufacturing
process
tests,
educational
experiments
and
testing
facilities.
For
the
external
control,
the
pin
ofdigital
I/O
interface
not
only
provides
the
signal
output
frequently
used
by
the
compare
function,
but
also
allows
users
to
define
signal
output
for
each
pin.
Under
the
self-definition
mode,
users
can
apply
the
I/O
as
a
simple
digital
hardware.
The
external
control
requirement
can
be
achieved
by
signals
from
each
pin
so
as
to
help
users
reduce
trouble
of
making
hardware.
With
respect
to
remote
control
and
retrieving
data,
GDM-8351,
taking
consideration
of
users‘
habitual
practice
and
universal
system
interface,
provides
standard
RS-232C
and
USB
interface
to
edit
control
programs
and
read
measurement
results.
It
is
worth
noting
that
for
utilizing
the
USB
interface,
users
have
options
of
selecting
either
USBCDC
or
USBTMC
mode.
While
USBTMC
is
selected,
users
are
able
to
control
instrument
with
the
USB
interface
exactly
the
same
as
controlling
instrument
with
the
GPIB
interface;
therefore,
the
relatively
expensive
GPIB
connection
cable
is
no
longer
required.
